OK - a few weeks ago the wife said the door opened on its own. I checked with the kids that have the apps on their phone and no-one did this. As I was not there, I cant vouch for it.
HOWEVER, I was just washing the car and the garage closed on me - only a few minutes before, I had my new Audi S3 half in and half out - I would NOT be happy if it closed on its own only a few minutes before. I checked all the usual people - no-one did this. I think it is therefor imperative that we have some sort of central application logging for open/close commands and from which device as this could be a security nightmare. I am not implicitly blaming the garadget as it could be an issue with the garage door opener or a short in the switch itself - but the garadget log of open/close commands sent would have proven this one way or another. The garadget apps have NOT been used to open/close at all today (Australia 2 June) so it would be easy to see one way or another.
